Evaporative cooling common issues and problems

Start up

When the cooling is first turned ON, there will normally be a delay before the cool air is delivered from the duct outlets. The delay will vary depending on the brand/model of cooler, but this doesn’t mean the cooler is not operating. Most coolers have pre-programmed delay times, to allow fill up the Cooler’s tank with water and/or Pre-wet the filter pads. The entire process can take up to 10 minutes before cool air is expected from the duct outlets.

Shut down

Many modern cooling units fitted with a dump valve, there is also a delay in emptying the water from the Cooler’s tank for a period after the unit has turned OFF at the end of use. Some models have an additional pre-programmed tank wash cycle. This washes the tank with clean water at the end of use.

If you’ve noticed that it takes Cooler too long to Start up, or it’s continuously leaking water outside of operating cycle - might be there is a problem and it’s a good idea to get it checked by a Licenced Technician.

Q. How often should the cooler be serviced?
A. All manufacturers recommend the cooler is serviced every 2-3 years to ensure it operates at peak efficiency

Q. The air smells a little different. Why?
A. New Cooling pads can give off a mild odour while they are settling in. It may also be indicating that the unit requires a service

Q. How much water does my evaporative cooler use?
A. The amount of water an evaporative cooler uses is dependent on the evaporation rate of the coolers pads. On a hot day cooler may refill every half an hour

Q. Can I run the system when I am not home?
A. Evaporative cooling relies on doors and/or windows being open so you can run it when you are not home, provided you have the required ventilation openings

Q. How many doors and windows should I have open?
A. Refer to the owner’s manual section on openings required, it also gives suggestions on how to provide this. At least one door must be open

Q. Why is there condensation and moisture on my tiles and furniture?
A. Make sure the vents are directed across the room and not towards the floor. Make sure sufficient doors and windows are open. If it is a humid day turn the pump off.

Q. There is no air coming out of some of the vents
A. It is highly probable that this is an installation issue. Please contact your installer in the first instance

Q. How far should my cooler be away from sanitary vents?
A. The unit should be at least a 5m radius away from a sanitary outlet.

Q. How cool is cool?
A. The degree of cooling available from any type of air conditioning, is dependent on the outside weather conditions. Your Evaporative Cooler works best on hot, dry days. If system functioning properly you should expect at least 10 Degrees Celsius in temperature difference.

Q. Should water be coming out of my evaporative cooler during operation?

    This man is one of the best tradies I have encountered.
    Polite, punctual and most of all is an expert at what he does at a very reasonable price.
    Last year he serviced my Brivis evap. cooler. He took before and after photos as I wasn't getting on the roof for an inspection haha. This was his idea and I'd never thought about it.
    He brought all the panels down for a good scrubbing. Other plummers have only hosed them down on the roof.
    All in all, a very thorough tradesman.
    This year Serge replaced my four vents in the house. They look terrific, and have a shiny finish for easy cleaning. He cleans up and takes all the rubbish with him
    I'll happily refer him to my friends with confidence.
    Thanks again Serge
